To all 'whm 'it may coacem.'

Be it known that I, OSCAR E.v SERvIs, a citizen of the United States, residing in Chicago, in the county of'Cook and State l of Illinois, have invented a new and useful Improvement in Electrode Suspension Devices, of4 which the following is a specification. .This invention relates to ,a suspension device for electrodes and has for objects the provision of a suspension device by which electrodes of standard form and construction may be adjustably suspendedfrom the conductor rod into an electrolytic bath, so l5 that the position of the electrode in said bath maybe readily adjusted to accommodate varying top levels Aof the bath and wearing away of the electrode, and also to provide a suspension vdevice constructed to 80 make a sure gripping contact with the conductor rod.

In addition to the general objects recited aboye, the invention has for further objects such other improvements or advantages I5 in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In the accompanying drawings forming a part of this specication, andshowing,

' 30 a preferred form and manner in which the invention may be embodied and practiced, but without limiting .the claimed lnvention specifically to such illustrative instance or instances:

"Ihe device of the present invention is epecialy constructed for suspending anodes the standard bar type, and for convenience the present descrlption will be con. lined to this use of the invention. Features vice for l f Vespecially'-adaptable for use. in connection Flgure l is an elevational view showing. the lnventionapplied 4to bar .anodes of'V showing the sus-- of construction and operation are, however, adaptable to other valuable applications, for

example to anodes of other types and to othe'i` electrodes; consequently, the scope of the mvention is not confined to the specific use and specific embodiment herein described as an illustrative example. 00 Referring to the drawing, there is shown at 11 a standard bar anode, said anode embodying in its construction the usual shank 12Aof -reduced diameter with respect to the main body portion of the anode and byV which the anode is'suspended from the con-v ductor rod 13 of an electrolytic bath, indicated diagrammatically at \14. Heretofore it has been customary to construct the reduced shank 12 of theanodeof ductile and easily bendable metal and to bend said shank A 12 into the forml of a hook that is hooked l over the conductor bar 13 to suspend the anode'in the electrolytic bath. This practice is not only clumsy and tedious and admits of no uniformity in the relative positions 4 l of several anodes suspended in ythe, bath, but

' also offers the serious objection that no adf 'justment of the position of the anode can be made to compensate for varying levels.,v of the top surface of. the bath and for Wear-y ing, away of the. anode by electrolytic decomposition. I 1 The 1present invention'` provides an exceeding y simple and efective suspension deelectrodes of this nature which is with v'anodes of the standard'bar construction L4described aboveand not only provides for the securesuspension of such anodes in an no.' electrolyticf""bath without any departure whatever in the construction' of the anodes themselves, but also has the additional advantage of/permitting the anode to be ad. j usted vertically relatively to the suspension device so as to admit of absolute regulation gf .the height of the anode in the electrolytic ath. As shown in Figs.. 1 to 4 inclusive of the drawing, the improved suspension device of Y the present invention embodies in its construction a. sleeve member 15 from the upper end of which extends a curved. bar member Y 16 that is bent downwardly at its top to form a'hook 17. The sleeve member 15 of 105 the suspension device is provided with a e one side of socket 18 extending longitudinally of: the axis of said sleeve member and adapted to -receive the standard shank 12 of an anode -11, as shown. Extending inwardly from the sleeve member 15 are two set screws 19 which may be respectively .screwed into the socket 18 to grip the shank 12 of an anode inserted into said socket 18 and thereby to hold the anode shank securely Nl() in said socket. A curved lear` spring. 2()- 15 threaded `socket 23 in the aforesaid bar` provided with a slot 21 is secured against the inner face of the bar member 16 by means of a setscrew 22 passed through the I' slot 21 of the spring and screwed into a member. At its upper end the spring is formed with a downwardly bent, portion 24: adapted to engage a portion of the circumyference of the conductor rod 13 and hold the 20g susension devicerigidly on the conduct/ or rou In utilizing the suspension device ofthe invention, the two set screws 19 are loosened 'and the electrode shank 12 is inserted into 2c the socket 18 of the suspension device.

When the proper relative positions of electrode and suspension device have been ate tained, the set screws 19 are tightened to secure the electrodeto the suspension device.

90 The electrode may then be readily suspende0 e made,

ed from a conductor rod, such Vas indlcatedat 13, by hanging the hook 17' at the top of the suspension device on'the conductor rod. In practice the spring 21, as well as the-hook Se -portion and sleeve portionsoi the 'suspension device will be made of conducting material, and when the suspension device has been applied to the conductor rod, a three oint conducting contact with such rod will thereby insuring passage of the lcurrentinto the body of the electrode. The

small spring construction combined with the hook formation of the suspension device secures a rigid suspension from the conductor rod and'prevents wabbling ofthe electrode in thel bath. f

In the form ofthe invention illustrated in Fig. 5 the upper end of the rod portion 16 of the suspension device is provide with a 50 hooklike member 25 bent oppositely from thehook 17. This member 25 is of particular value when the suspension device is apvplied to a cathode tray, for the purpose of ifting the articles supported by said tray en f from the electrolyticbath. The suspension device shown'in Fig. 5 is moreover provided with only one set Screw 19 for gripping the shank of the electrode instead'of the'two set screws illustrated in the other figures. Ex-

@c cept as hereinmentioned, the construction andoperation of the device illustrated in v Fig. 5 is the vsame as that of thel other figures. Y
